Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468492, here are decompositions:

89 + 31468403 = 31468492
101 + 31468391 = 31468492
173 + 31468319 = 31468492
233 + 31468259 = 31468492
269 + 31468223 = 31468492
281 + 31468211 = 31468492
479 + 31468013 = 31468492
491 + 31468001 = 31468492

Showing the first eight; more decompositions exist.
